Why do X-rays require careful handling in medical applications?
**X-rays in medicine** treat certain cancers because high-energy photons ionize and damage DNA of malignant cells, also imaging because bones absorb more than tissue, contrast. Gamma rays from Co-60 used for radiotherapy, energy ≈1.17 and 1.33 MeV, highly penetrating. X-rays have high energy and penetrating power, which can damage living tissues and cause cellular mutations, necessitating careful handling to avoid overexposure. Using c = fλ, E₀/B₀ = c, I_d = ε₀ dΦ_E/dt, and spectrum classification λ = c/f, evaluation yields Potential tissue damage, illustrating EM wave transverse nature and Ma
